If you have it working on the N2 it seems that the server is working properly. Please check the IP you used in the tvh client in the other devices. If your server’s up has changed they won’t work.
PS: in the devices that act as clients, forget about the drivers, they’re for the server device.
It might but check what’s the IP of the server and check if the IP in the configuration of tvh client is the same. Also check if the login and pass is correct if you have them in the tvh server.
